Core Tip

Core Tip: Gastric metastasis from renal cell carcinoma (RCC) is an extremely rare clinical entity that may be missed or misdiagnosed due to lack of knowledge. We present a case of metastatic gastric tumors arising from RCC 5 years after radical nephrectomy. Simultaneous, multifocal metastases to the gallbladder, pancreas and soft tissue were detected. This case highlights the dynamic changes in white light endoscopy and endoscopic ultrasonography, demonstrating the tumors’ growth pattern during the 1-year follow-up. Our diagnostic excision approach using endoscopic submucosal dissection has been rarely reported in this entity.
